DNA DNA. Short for deoxyribonucleic acid. The nucleic acid that is the genetic material determining the makeup of all living cells and many viruses. It consists of two strands of nucleotides linked together in a structure resembling a ladder twisted into a spiral.eoxyribonucleic acid, commonly called DNA, exists mainly in the nucleus and mitochondria of each cell in an organism. It consists of two long strands linked together in a structure resembling a ladder twisted into a spiral, called a double helix.

- DNA -> DNA. DNA -> RNA. Replication is the process in which a cell makes an exact copy of its own DNA (copy DNA -> DNA). Replication occurs in the S-fase in preparation to cell division during which the genetic information for the synthesis of proteins is transfered from the mothercell to the daughtercell.

DNA DNA. DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes.NA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide.

DNA, Genes and Chromosomes DNA. DNA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses. It belongs to a class of molecules called the nucleic acids, which are polynucleotides-that is, long chains of nucleotides.Each nucleotide consists of three components:he nucleus of each cell in our bodies contains approximately 1.8 metres of DNA in total, although each strand is less than one millionth of a centimetre thick. This DNA is tightly packed into structures called chromosomes, which consist of long chains of DNA and associated proteins.

Chinese Vegetables Cabbage and Chinese cabbage (Brassica rapa, Pekinensis Group) are cool-season vegetables that should be grown in early spring or fall. They grow best at temperatures of 60 to 65 °F.Chinese cabbage forms dense heads that may be very upright and tall (Michihili types) or round and barrel-shaped (Napa types). The leaves are slightly wrinkled and thinner than the leaves of regular cabbage with wide, crisp midribs.abbage and Chinese cabbage (Brassica rapa, Pekinensis Group) are cool-season vegetables that should be grown in early spring or fall.
